Meyer rolls two fair, ordinary dice with the numbers 1,2,3,4,5,6 on their sides. What is the probability that exactly one of the dice shows a square number?
Perfect squares would be 1 or 4
for ONE die
1 2 3 5 6
4 2 3 5 6
The same for the other die
so out of 36 possible rolls there are 16 rolls where ONE die has a square 16/36 = 4/9
